中文摘要: 采用臭氧氧化法对某金矿氰化渣产生的含氰废水处理进行了试验研究。主要考察了在一定臭氧浓度条件下,氧化反应时间、反应pH值、催化剂等因素对氰化物去除效果的影响,并确定了最佳反应条件。试验结果表明,采用臭氧对该含氰废水进行氧化处理,在pH=7.0、不添加催化剂,反应时间为75min时,废水中游离CN-最大去除率达96.3%,总CN-最大去除率达92.3%。
Abstract:Cyanide waste water was treated by using the O3 oxidation method from a certain gold mine of cyanide residue.Mainly investigated under the condition of same O3 concentration,oxidation reaction time,pH,catalyst,etc factors on cyanide removal effect and the optimum reaction conditions were determined.The results showed that under the conditions of without catalyst,the value was 7.0,reaction time was75min,the removal rate of maximum CN- was 96.3%,and the total CN- was 92.3%.
keywords: cyanide waste water O3 oxidation removal rate
